Hi,

I am quite new in the “video” world, so I might say some nonsense..

I am wondering why the maximum is 72dpi for video even at highest resolution.
Is there a technological limitation?

So, what does it change from 2K and 1080p for example if I keep the same FOV of my GoPro?
In principle I was expecting to get higher resolution (pixel/inch ) on the horizontal axis for example.
Almost double than 1080p.
But if the pixel/inch is fixed to 72 than what’s changing?
I mean, if I get the same number of pixel to reconstruct the image of the same dimension (same FOV)
what is changing form 2K and 1080?

Once again, sorry for the maybe “studio” question , the answer might be hidden in the decoding
action on the different video, but honestly I do not know.

Thank you for any explanation

Max
